Agate is a type of chalcedony quartz that forms in layers. The stone comes in an array of colors and textures. The colors and layers are why agate is such a versatile and unique stone. The teardrop shaped green agate stone in this sterling silver pendant has great contrasting bands. The dark green disappears into the gleaming white. The stone is bezel set in a hinged sterling silver pendant and is pearl accented. The pendant hangs 2.15 inches from an 18 inch sterling silver Italian box chain.
